Happy Birthday, January Jones! The gorgeous blonde starlet—born on January 5, 1978— is celebrating the big Three-Four today, but you’d never know it from her youthful appearance. Here’s hoping the New Year is relaxing for the Mad Men actress, since 2011 kept her incredibly busy. In addition to starring alongside Liam Neeson and Diane Kruger in the big-screen thriller Unknown, Miss J tackled the role of Emma Frost in X-Men: First Class. Oh yeah, and let’s not forget the fact that she also had a baby last fall. Her infant son, Xander Dane Jones, was born September 13.

January hasn’t yet revealed his father’s identity, but ex-flame Jason Sudeikis, an actor/comic best known as a regular cast member on Saturday Night Live, suggested he’s the baby-daddy when he hosted the MTV Movie Awards last summer. “I have a lot of pressure on me, okay?” he reminded the audience. “I have 10 minutes left in the show, I might be a dad soon…” No one knows for sure, but if Jason’s a proud papa he’s certainly not sitting home reading parenting guides. He’s been spotted out and about with House alum Olivia Wilde. Ah, Hollywood—the love triangles never surprise us! Anyway, January looks unscathed and as glamorific as always as she gets ready for some yoga in these Versace sunglasses, which are available in three fun and funky color choices.
